SPECIFICATION forming part of Letters Patent No. 384,918, dated June 19, 1888.

Application filed Ju y 16, 1887. Renewed May 24, 1888. Serial No. 274,946. ,(No model.)

To all whom, it may concern:

Be it known that I, CHARLES C. LEMLEY, a citizen of the United States, residing at Merrill, in the county of Lincoln and State of Wisconsin, have invented new and useful Improvements in Flue-Thimbles, of which the following is a specification.

This invention has for its object to provide novel means for securing smoke-pipes in fluethimbles; and to such end the invention consists, essentially, in the combination of a fluethimble having its outer end provided with an internal circular groove having lateral slot, .a spring-wire arranged in said groove with one part secured in a stationary position and one end extending laterally through the aforesaid slot as a crank-arm, and 'means-such as a pivoted lever-eccentrically connected with the end of the crankarm extending through said slot, so that the spring-wire can be drawn and tightened against the external surface of a stove pipe inserted in the thimble.

The invention also consists of certain other features of construction hereinafter described and claimed, reference being made to the accompanying drawings, in Which- Figure 1 is a perspective view of a due thimble illustrating my invention; Fig. 2, a transverse sectional view taken centrally through the groove at the outer end of the thimble, the spring being shown by dotted lines in position to bear upon a stove-pipe inserted in the thimble; Fig. 3, a perspective view of the spring-wire and its operating-lever detached from the thimble.

In order to enable those skilled in the art to make and use my invention, 1 will now describethe same in detail, referring to the drawings,where the numeral 1 indicates a cylindrical flue-thimble having its outer end rolled or otherwise provided with an outwardly-pressed annular head, 2, forming an internal annular groove, 3, said bead being punched or pressed, with a slot, 4, and orifices 5 and 6, arranged at different points in the bead. The spring pipe-holding wire 7 is located in the groove, and one end is bent laterally to form a lug, 8, which engages the orifice 5, and a leg, 9, which engages the orifice 6, while the other end of the wire extends through the slot 4 and is bent laterally into a crank-arm, 10, located outside the thimble. The lug s ehd leg 9 hold the wire The by a pivot, 12, a swinging lever, 13, which is eccentrieally connected with the crank-arm by the end of the crank-arm loosely engaging the lever at one side of thepivot 12, the portion of the lever at the other side of the pivot comprising a handle by which to swing the lever. If a stove-pipe be inserted in the thimble while the wire is entirely within the groove and the lever be swung outward, the crankarm is moved inward and drawn in the slot 4 toward the lug 8, and with such crank-arm the greater portion of the wire between the crankarm and the leg 9 is moved inward, (see dotted lines, Fig. 2,) thereby pressing upon the stove-pipe with sufficient spring-pressure to securely hold the pipe in the thimble. A reverse movement of the lever will release the the thimble a stove-pipe having an annular,

depression into which the spring-wire can be clamped, but do not confine myself thereto.

When the lever 13 is drawn around to press the wire 7 upon a stove-pipe, the lever must be moved until it bears against the flue-thimble 1. This movement throws the upper end of the crank 10 to one side of the pivot 12 and in a'plane, or substantially so,with a line taken lengthwise through the center of the lever 13 and its pivot 12. practically locked, and the resiliency of the spring-wire cannot move the lever until the latter is swung outward from the flue-thimble.

Having thus described my invention, what I claim is- 1. The combinatiomwith a flue-thin1ble having at its outer end an internal groove and a lateral slot, of a circular spring-wire arranged in said groove, with one part secured in a stationary position and one end having an arm spring-wire, substantially as described.
